In the latest case of the Facebook giant, the social networking site has admitted to collecting information about 1.5 million users without their knowledge.
The largest social network in the world said on Wednesday that their e-mail contact lists had been “unintentionally” uploaded after changing the design of the site about two years ago, speaking the company was now working to delete them.
Facebook, according to the network “CNN” on Thursday, that the problem began years ago, when changes were made to the verification process that users go through registration, to get a personal account.
Before these changes, users were given the option to upload their email contact lists when they opened an account to help them find friends already on Facebook.
But in May 2016, Facebook removed options that show user contact lists and move them to corporate servers, which means that some cases have downloaded people’s email contact lists on Facebook without their knowledge or consent.
